I respectfully disagree, not until there is a better way to browse missions that won't be so focused on missions at "the top."

I definitely agree that the search tools need to be improved. However, you can use the custom option to help improve your search. Considering there is an option for no tip, I don't see why anyone would actually disagree with th4e chance to reward the missions they enjoy with a better reward. If he were offered the chance to tip Cryptic missions, I know I'd be leaving no tip on a lot but some, like episodes 4 and 5 of the Devidian series would definitely get a nice tip from me!
